Coaxial cable Rangeful SMA male to PL259 UHF RG58/U 50 Ω, 2 m

Coaxial cable Rangeful SMA male to PL259 UHF RG58/U 50 Ω, 2 m is a 2‑metre RF connection cable with an SMA male connector on one end and a PL259 (UHF) plug on the other, assembled on standard RG58/U 50‑ohm coaxial cable. It is intended for signal transfer between radio transceivers, antennas, antenna tuners and test equipment where 50 Ω impedance is required. The cable construction balances flexibility for routing with the electrical characteristics of RG58/U to support HF and VHF/UHF applications within the limits of RG58/U performance.

Advantages

This Rangeful SMA male to PL259 UHF cable provides a compact SMA interface and a widely used PL259 UHF plug for compatibility with many amateur radio devices and test instruments. The 50 Ω impedance ensures impedance matching for most transceiver and antenna systems designed for 50‑ohm operation. At 2 metres length the cable is convenient for bench connections and short antenna runs while the RG58/U braid and dielectric construction maintain consistent signal transfer and shielding typical of this cable type.

Suitable for

• Connecting amateur radio transceivers to antennas or antenna tuners
• Linking test equipment such as spectrum analyzers or signal generators with 50 Ω ports
• Temporary or bench RF setups requiring SMA to UHF (PL259) conversion
• Portable radio installations with short coaxial runs

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Connector (end A): SMA male
• Connector (end B): PL259 UHF male
• Length: 2 m
• Typical use: RF signal transmission for HF/VHF/UHF within RG58/U frequency suitability

How to use

Install the cable by firmly connecting the SMA male end to the SMA female socket and the PL259 plug to the corresponding SO‑239 socket, ensuring threaded connections are properly engaged to maintain good electrical contact. Route the cable to avoid sharp bends with a bend radius appropriate for RG58/U to prevent deformation of the dielectric or shielding. For laboratory or field use, verify connectors are clean and free of corrosion before connection. When disconnecting, unscrew connectors rather than pulling on the cable jacket to reduce mechanical stress on terminations.

Usage recommendations

For best performance, keep the cable length as short as practical for your setup to minimize insertion loss. Avoid exposure to prolonged moisture and extreme mechanical strain; if used outdoors, consider additional weatherproofing at connector joints. Confirm that the connected equipment expects a 50 Ω interface to maintain proper impedance matching and reduce risk of signal reflection.
